Safety audit at traffic signal junctions

Road safety audit is a process for checking the safety of new schemes on roads. It is important to remember that it is NOT a check on technical or design standards. As the objective of safety audit is to minimise future accident occurrence and severity the auditor should set out to ask a simple question - 'who can be hurt here and why?' This paper visits the basic safety principles that have to be taken into account when installing traffic signals, describes the most frequently identified issues during safety audits and looks at the problems that arise when the auditor is confronted with an innovative scheme with no 'control' data to benchmark safety issues and no experience of this type of scheme.
